When I try to select and drag a rectangle, it shows me a weird result but when I drop it, it moves correctly.
It seems there is a problem with the QuickMove visual helper.
QuickMove factory couldn't handle repeated points in an element. It always cloned the first one of the equal list and moved it twice (or three times or more).
Fixed on repository version 1569.
